Abstract

1,219,224. Cavity coating device. AGFAGEVAERT A.G. 12 Feb., 1969, No. 7574/69. Heading D1L. A web 1 is coated, during passage round a roll 2 with a viscous liquid from a cavity coating device 3 whose inlet gap 8 is sealed from the atmosphere by a blocking vacuum chamber 9 evacuated through a pipe 14 containing an adjustable baffle 15 across which exists a pressure drop in the ratio of 2:1 in the direction of flow of air.
